Download the Congress 2023 Mobile App!

The CAO Congress 2023 mobile application is now available for download! You can access the app via the Web (mobile/desktop), iOS, and Android. You must be a registered delegate to access the event within the app. Once you have downloaded the app, the Congress 2023 event should appear. Click on it to access our content and ensure you enter the unique password supplied to you in the email announcement regarding the mobile app.


Your password to access the mobile app is NOT the same as your password for the registration system. Please use the unique password supplied to you in the email announcement regarding the mobile app. If you have misplaced this email, click on the "Forgot Password" link on the app login page. If you are still experiencing issues, contact for assistance.

Click on the navigation menu and scroll to the bottom. Click on "Settings" and then choose the "App Settings" header. The current language will be displayed above the dropdown box. Click on the dropdown box to change your selected language.

Your profile within the mobile app only consists of your name, organization and title, though you can choose to upload your own photo and additional details. Your profile will NOT be visible if you opted-out of the Contact Information Disclosure during registration. Otherwise your profile will be visible. You can change this setting at any time. Click on the navigation menu, scroll to the bottom and select "Settings". You will be presented with your profile, and at the bottom are various settings which you can control. Toggle on or off the "Allow my profile to be publicly visible" as desired.

Yes, the session selections you made during registration have been transferred into the mobile app so that you will have your own personalized calendar. Click on the "My calendar" button from within the Schedule page to see your selections. Your sessions will also appear with a bookmark icon when browsing through the schedule. Click on the bookmark icon for any session to add to your calendar.

Please note: because the two systems are not connected, any changes you make in the app will not be translated into the registration system and vice versa. However, session selections are for space planning only and selection within the app or registration system does not guarantee a seat onsite. All sessions are seated on a first-come first-served basis during the conference.

The schedule is grouped by day, and shows all sessions in both the OD and OA streams as a default. To see everything in one particular stream, use the "Filters" button at the bottom of the screen and select which stream you want to see. You can also use filters to see in which language sessions are presented.
